Best Low Calorie Vegan Protein Bars

SimplyProtein’s Peanut Butter Chocolate builds flavor from real peanuts and unsweetened chocolate, then holds it together with soy protein crisps—soy protein isolate puffed into crunchy bits.

The label stays tight: seven core ingredients by our count, plus three functional add-ins that lean on chicory-root inulin and acacia (plant fibers) and a touch of plant-derived glycerin (a syrup that keeps the bar soft) to keep sweetness gentle without artificial sweeteners.

Fats come mostly from peanuts, with small amounts of peanut and sunflower oils; carbs come from brown rice crisps and a little cane sugar, with those fibers adding body and mild sweetness.

It’s vegan and gluten-free, and it eats like a light, crisp snack rather than a dense meal replacement.

Promix’s Mexican Hot Chocolate Protein Puff Bar leans on whey isolate and concentrate, plus a little egg white, to deliver 15g of complete protein in an unusually light package: 140 calories with just 3g of fat.

The carbs are quick and modern—tapioca starch (a fast‑digesting starch from cassava) and organic tapioca syrup—tempered by soluble fibers like tapioca fiber and inulin (refined fibers that add body) plus a touch of glycerin, a plant‑derived syrup that holds moisture so sweetness can stay at 4g of sugar.

The flavor reads classic cocoa with a twist: dutched chocolate for smoothness, cinnamon and vanilla for warmth, sea salt, and a whisper of chipotle heat. It uses a short list of four purpose‑driven helpers—think a sunflower‑based emulsifier and a seaweed‑derived gelling fiber—to keep the puffs crisp yet cohesive.

Big picture, it eats like an airy, crunchy snack rather than a dense meal bar, ideal before or after a workout or anytime you want chocolate with a little warmth.

Maximuscle’s Chocolate Cookie and Milk builds its macros around milk proteins—casein and whey—with a small assist from soy and collagen, landing 16 grams of protein in a bar that eats like dessert.

Its label sugar stays low at 1. 7 grams because sweetness comes primarily from maltitol, a sugar alcohol, with a tiny backup of sucralose.

The unmistakably chocolate‑and‑milk character is driven by cocoa powder/cocoa butter and a soft, milky filling made with shea butter and whole milk powder, which is why the texture reads creamy rather than chewy.

Calories stay under 200, and the carbs are more engineered than oat‑or‑date based, which helps keep sweetness steady without a big sugar surge for many people.

IQBAR’s Almond Butter Chip leans fully plant-based, anchored by pea protein and real almonds, with unsweetened chocolate and cocoa butter bringing the chocolate note. It’s built as a low-carb, higher‑fat snack that draws steady energy from nuts and cocoa fats rather than sugar, and it’s gently sweetened with a touch of stevia.

The ingredient list is short and largely pantry‑familiar, with minimal additives and no sugar alcohols. Bonus: you get a full day’s worth of vitamin E, plus meaningful iron and magnesium from the almond‑cocoa base.

Raw Rev’s Chocolate Chip Cookie Dough goes all‑in on plant ingredients: a pea‑and‑rice protein blend tucked into a cashew base, warm vanilla, and real organic dark chocolate chips. At 180 calories with 11g of protein and 20g of carbs, it leans on a tapioca‑derived prebiotic fiber for structure and mild sweetness instead of straight sugar.

Fat runs a bit higher from nuts, seeds, and a touch of coconut oil, which is why the texture reads doughy rather than chalky. Sweetness stays modest—mostly monk fruit, with a little cane sugar in the chocolate chips—so the effect is dessert‑ish without a sugar rush.

It’s a concise ingredient list with about four functional helpers to keep things soft and the chocolate behaving, all in a dairy‑free, gluten‑free package aimed at steady energy.

Vegan bars that aim for keto are uncommon, and this one leans into the classic peanut-butter-and-chocolate lane with real peanut butter, peanut flour and extract, plus dark chocolate chips. Its 11g of protein comes from a plant blend—pea protein isolate tucked into cocoa crisps with brown rice protein—and a small boost from the peanut ingredients.

To keep sweetness in check, it uses soluble tapioca fiber and allulose instead of cane sugar, landing at 1g of sugar with a gentler blood-sugar impact for most people. Fats (11g) come mostly from peanuts and almonds, with cocoa butter lending that chocolate-chip snap and a modest iron bump from the cocoa and plant proteins.

A short list of refined helpers—glycerin for softness and sunflower lecithin for smooth mixing—keeps texture pleasant without piling on additives.

Think trail snack first, protein bar second: dates and raisins form the base, gluten-free oats add chew, and freeze-dried raspberries bring that tart pop.

Protein comes via crisp soy pieces—light and crunchy instead of dense—while additives stay minimal, with a little tapioca starch to hold the crisps and rice starch plus natural flavorings to keep the berry notes consistent.

Macros lean toward quick energy: higher carbs and sugars, very low fat, and modest protein. The sweetness comes entirely from fruit, including apple, pear, and grape juice concentrates—flavors your tongue reads as fruit, but sugars your body absorbs quickly.

Huel builds a cookie‑dough moment from a fully plant‑based protein blend—wheat gluten for structure and chew, with pea, soy, and rice proteins rounding out the amino acids—under a chocolatey coat with real chips.

At 178 calories with 13g protein and just 2g sugar, it leans on modern food tech for texture and sweetness: soluble corn fiber (a refined fiber that resists digestion), maltitol (a sugar alcohol that tastes like sugar but contributes fewer calories), and a touch of glycerol to keep it soft—no high‑intensity artificial sweeteners.

Fats come mainly from refined sunflower oil and cocoa butter, with a small whole‑food nudge from ground flaxseed, so the fat profile skews mostly unsaturated. The quiet flex is the micronutrient fortification—vitamins D3, K2, C, E, a B‑complex, and minerals—showing up at meaningful daily values.

Atlas leans into peanut butter and dark chocolate but rewrites the sugar script. The protein is fully plant‑based—a rice‑and‑almond base with crunchy pea‑protein crisps—boosted by peanut butter and peanut flour.

The chew comes from soluble tapioca fiber (a refined binder from cassava) and a little plant‑derived glycerin to keep things soft, while sweetness relies on allulose, a low‑calorie sugar that behaves like the real thing, plus concentrated monk fruit extract.

Fats are mostly peanut‑driven, with small amounts of cocoa butter and coconut oil for structure. Net result: a vegan, gluten‑free, keto‑friendly bar with 15 grams of protein, 180 calories, only 0.

5 grams of sugar, and a quietly impressive 38% Daily Value of iron from the cocoa components.
